ERASTUS TRACY, OF POUGHKEEPSIE, NEW YORK.

MACHINE FOR CLEANING BURS FROM WOOL ON THE- SKIN'.

Specicaton of Letters Patent No. 526, dated December 20, 1837.

T0 all whom it may concern Be it known that I, EnAsTUs TRACY, o-fPoughkeepsie, in the county of Dutchess and State of New York, haveinvented a new and useful machine for the purpose of cleaning the bursfrom the wool on the sheepskins, as imported from South America andother places; and I do hereby declare that the following` is a full andexact description thereof.

I construct a frame, such as is represented at A, A, in the drawing,upon which I mount a cylinder B, which may be two feet long, and onefoot in diameter, or of such other dimensions as may be preferred. Uponthis cylinder, I place four, or any other convenient number, rows ofteeth, which should be made of steel; These teeth should be about aninch long, and stand about an eighth of an inch apart. They may be cutupon plates of steel, or they may be set separately into the cylinder.This cylinder is to be made to revolve with a rapid motion, toward theendless apron C, upon which the skin to be operated upon is to be laid.

The two rollers around and with which this endless apron revolves areplaced in a separate frame D, which is made to slidel back and forthupon the frame A, by means of the rack and pinion A, A. The endlessapron is made to revolve by hand, by means of the winch E, attached tothe front roller. Immediately above this latter roller` thereL is apressing roller F, which is to be borne down by means of weights orsprings; and between this and the endless apron the skins to be operatedupon are held.

In using this machine, the frame D, is to be moved back from thecylinder B, the skin to be cleaned is then placed upon the endlessapron, and the winch E, turned so as to pass it about half way throughbetween the roller F, and the apron, the frame D, is then moved towardthe revolving cylinder, so that its teeth shall take into the wool, thewinch is then turned so as to withdraw the skin, the other half of whichis then subjected to the same operation with the first, and it will befound to be perfectly cleaned, without loss of, or injury t0 the wool.

f I claim as my invention, and ask a Patent The above described machinefor cleaning wool on the skin from burs; that is to saya machine havinga revolving cylinder furnished with teeth, to which the skin, placedupon an endless apron, is tobe fed up, and operated upon, as herein setforth.
